http://www.ebay.com/itm/170831336660?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649 small tent but gonna throw my 400 watt hps/ mh for my first grow!
You will want either a cool tube or an air cooled hood. I like the 6" block buster as it has a great foot print in the tent and coupled with a 6" hurricane fan, it helps keep the temps down. Once in flowering I will also incorporate a 250 cfm intake fan so when she is closed it wont let light in and cave my tent in if I am not around to adjust the fan speed controller. I have a wall mount fan, could not find clip on fans that oscillate, and will have a tower fan in there once the girls get bigger.Move the air with just fans? Would clip on fans be a good bet? Or.. outside air for cooling?
